Mass flow meter detection device

Abstract

The quality flowmeter detection device belongs to the technical field of quality flowmeter detection, and aims to solve the problems that the existing detection structure has certain error influence and the detection process is time-consuming and low in work efficiency because the quality flowmeter needs to be fixed to prevent water pressure from being too large to cause the quality flowmeter to shift before detection in actual operation process. The quality flowmeter detection device uses the air pump to extract detection water from the water storage tank, and the detection water flows through the quality flowmeter, so that the pressure resistance strength detection of the quality flowmeter is completed. After the detection is completed, the quality flowmeter comes out of the external interface, and then the new quality flowmeter is placed on the placing part, is conveyed through the conveying belt, and the pressure resistance strength detection is completed again. Compared with the prior art, the detection step is simpler and more convenient, the error is smaller, and the work efficiency is greatly improved.

Description

Technical Field

[0001] This invention relates to the field of mass flow meter testing technology, and particularly to a mass flow meter testing device. Background Technology

[0002] A mass flow meter is a flow meter used to measure the mass flow rate or total volume of fluid at a specific cross-section. Based on their working principle, they are classified into four types: Coriolis mass flow meters, calorimetric flow meters, impulse flow meters, and other types of mass flow meters. Currently, after manufacturing, mass flow meters require pressure resistance testing to prevent damage caused by excessive pressure during use. This makes mass flow meter testing devices indispensable.

[0003] The current testing device involves connecting the mass flow meter to water pipes after its manufacture, adjusting the water pressure to 1.5 times the nominal pressure, and letting the water flow through the mass flow meter for five minutes. After the test is completed, the device is replaced with the next one. This process is quite cumbersome in actual operation because the mass flow meter needs to be fixed before testing to prevent it from shifting due to excessive water pressure. This results in a certain degree of error in the testing structure and makes the testing process time-consuming and inefficient.

[0004] Therefore, we propose a mass flow meter detection device. Summary of the Invention

[0005] The purpose of this invention is to provide a mass flow meter testing device, which solves the problem in the prior art where the current testing device connects the two ends of the mass flow meter to water pipes after it is manufactured, adjusts the water pressure to 1.5 times the nominal pressure, lets the water flow through the mass flow meter for five minutes, and then replaces it with the next one after the test is completed. This process is quite cumbersome in actual operation because the mass flow meter needs to be fixed before testing to prevent the mass flow meter from shifting due to excessive water pressure. This results in a certain degree of error in the testing structure and makes the testing process time-consuming and inefficient.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a mass flow meter testing device, comprising a main body and a conveying component disposed on the outer surface of the main body, a water storage tank for storing test water disposed at one end of the main body, a positioning component for fixing and pre-treating the mass flow meter to be tested disposed on the conveying component and the outer surface of the main body, and a pressure testing component for pressure testing of the mass flow meter to be tested disposed on the outer surface of the main body.

The water tank has a partition plate inside and a hinge on one side. The water tank is hinged to the main body. The interior of the water tank is divided into two identical storage chambers by the partition plate. The storage chambers have side wall panels inside and the outer surface of the side wall panels has angular slots.

[0007] Furthermore, one end of the main body is provided with a beveled part, and a recessed groove is formed on the outer surface of the beveled part. An electric push rod is provided inside the recessed groove, and rubber pads are placed at both ends of the electric push rod. Both ends of the electric push rod are connected to the recessed groove and the water tank respectively through the rubber pads.

[0008] Furthermore, a conveying groove is provided on the upper surface of the main body, and a through transverse groove is provided on the inner side wall of the conveying groove. The conveying component is placed in the conveying groove, and a bottom hole groove is provided at the bottom of the conveying groove. A triangular wedge is also provided at the bottom of the conveying groove. A collection inner groove is provided inside the main body, and the collection inner groove is connected to the bottom hole groove.

[0009] Furthermore, the conveying component includes a rotating part disposed inside the conveying groove, a conveyor belt sleeved on the outer surface of the rotating part, and a telescopic rod disposed inside the through transverse groove. One end of the telescopic rod is connected to the inner wall of the through transverse groove, and the other end of the telescopic rod is connected to the positioning component. An external interface is provided on the outer surface of the water tank, and one end of the conveyor belt corresponds to the external interface.

[0010] Furthermore, the positioning element includes a placement part disposed on the upper surface of the conveyor belt, an absorption part disposed at one end of the placement part, and an air blowing part disposed at the other end of the placement part, wherein the mass flow meter to be tested is placed on the placement part.

[0011] Furthermore, the placement section includes a soft pad plate disposed on the upper surface of the conveyor belt, a hard pad plate disposed on the upper part of the soft pad plate, a common pad plate disposed on the upper part of the hard pad plate, and a semi-circular arc clamping plate disposed on the upper part of the common pad plate. The soft pad plate has connecting areas on both the left and right sides of its upper surface. The soft pad plate is connected to a fixing plate for placing and fixing the absorption section and the blowing section through the connecting areas. One end of the fixing plate passes through the through transverse groove, and one end of the telescopic rod is connected to the fixing plate.

[0012] Furthermore, a T-slot is formed on the upper surface of the rigid pad, and a T-block is set inside the T-slot. The upper end of the T-block is connected to the common pad. A support rod is set on the upper surface of the common pad, and the common pad is connected to the semi-circular arc clamp through the support rod.

[0016] Compared with the prior art, the beneficial effects of the present invention are: The mass flow meter testing device proposed in this invention is cumbersome in actual operation of existing technologies. Before testing, the mass flow meter needs to be fixed to prevent displacement due to excessive water pressure, which introduces errors into the testing structure and makes the testing process time-consuming and inefficient. In contrast, this invention uses a pressure-resistant testing component, a conveying component, and a placement part to place the mass flow meter to be tested between two sets of semi-circular arc clamps and clamp it tightly. The two sets of clamping pipes are connected to the two ports of the mass flow meter, respectively, and an air pump is used to draw water from the storage tank. Water is extracted for testing and flows through the mass flow meter to test its pressure resistance. After testing, the mass flow meter exits from the external interface. A new mass flow meter is then placed on the placement unit and conveyed by a conveyor belt for another pressure resistance test. This process is repeated. Compared with existing technologies, this testing procedure is simpler and more convenient, produces less error, and greatly improves work efficiency. Furthermore, when assembling the clamping tube and the mass flow meter, the triangular wedge and bottom groove can collect water leaking from the clamping tube into the inner collection tank, reducing water waste.

The inner wall of the internal tube 423 has a mounting groove 4231, and the pressure detector 425 is mounted on the mounting groove 4231. One end of the internal tube 423 is inserted into one end of the mass flow meter to be tested, and is sealed to one end of the mass flow meter to be tested through a flange A424 sleeved on the outer surface of the internal tube 423.

The gas blown out by the main air pump unit 433 enters the interior of the mass flow meter to be tested through the transfer pipe 432. The diffuser 422 collects the gas and impurities coming out from one end of the mass flow meter to be tested.

[0033] Specifically, the mass flow meter to be tested is placed between two sets of semi-circular clamps 418 and clamped tightly. At the same time, one end of the adapter pipe 432 is connected to one end of the mass flow meter. The airflow generated by the main air pump set 433 is used to clean out the dust and impurities inside the mass flow meter. Meanwhile, the expanding mask 422 is aligned with the other end of the mass flow meter to absorb the blown-out impurities and dust into the collection tank 426. In addition, the built-in tube 423 is inserted into the absorption tube 427, and then the absorption tube 427 is connected to one end of the mass flow meter through the flange A424. The valve inside the built-in tube 423 is closed to keep the mass flow meter in a closed state. Gas is then introduced into the mass flow meter to keep the gas pressure constant. The gas pressure detector 425 can detect whether the gas pressure is constant. When the gas pressure fluctuates, it indicates that the mass flow meter itself is not sealed properly, assuming that the joint is sealed, and there is a quality problem, thereby improving the quality of the finished mass flow meter.
